Get Started with React Native

Reference for the Magic SDK for React Native: https://github.com/magiclabs/magic-js

Overview

The Magic React Native JavaScript SDK is distributed from the same NPM package as our Magic SDK for Web! This is your entry-point to secure, passwordless authentication for your iOS or Android-based React Native app. This guide will cover some important topics for getting started with client-side APIs and to make the most of Magic's features.

APIs from Magic SDK for Web are also available in the React Native bundle.

Magic can support either server-based or serverless web applications. It is up to the developers to implement the Admin SDK to validate the DID Token.

Installation

important

  • As of magic-sdk@2.0.0: React Native bindings are published as a separate NPM package.

  • As of @magic-sdk/react-native@2.0.0: the sub-dependencyreact-native-webview is removed from the package dependencies and required as a peer dependency to avoid IOS WebView module collision. Read more.

npm install --save @magic-sdk/react-native
# Ensure the required `peerDependencies` are installed
npm install --save react-native-webview@^8.0.0

Create an SDK Instance

Examples for the Magic Client SDK for React Native uses the ES Module/TypeScript pattern by default.

import { Magic } from '@magic-sdk/react-native';
const m = new Magic('API_KEY'); // ✨

Rendering Magic

To facilitate events between the Magic <iframe> context and your React Native application, a React component is exposed on your Magic instance: <Relayer>.

important

<Relayer> must be rendered into your application before Magic methods will resolve.

function App() {
return (
<View>
{/* Remember to render the `Relayer` component into your app! */}
<m.Relayer />
</View>
);
}

Usage With Ethereum/Web3

As with our web SDK, the React Native SDK can be used with Ethereum via Web3 or Ethers JS.

There's one "gotcha" to be aware of: @magic-sdk/react-native must be imported before web3 (this restriction does not apply to ethers). For example:

// 🚫 Bad!
import Web3 from 'web3';
import { Magic } from '@magic-sdk/react-native';
// ✅ Good!
import { Magic } from '@magic-sdk/react-native';
import Web3 from 'web3';

Set up web3.js

If you encounter this error: "Crypto" could not be found within the project

npm install --save node-libs-browser

Then, create a file called metro.config.js at the root of the project:

module.exports = {
resolver: {
extraNodeModules: require('node-libs-browser')
}
};
